The Hidden Power of Productive Disagreement

Without dissent, we all take the wrong turn

A few days ago, I stopped at a red light in Georgetown and saw a Subaru in front of me. One sticker, black letters:

"When critics go silent, the group gets stupid."

It made me laugh—and then think. Funny how one line on the back of a car says more about team dynamics than most leadership books.

We love harmony, it feels efficient and professional. But the research shows that psychological safety—the sense we can speak up without backlash—is the strongest predictor of team performance. It outperforms talent, budget, and even seniority.

Anyone who's worked with me knows I'm a straight shooter. I’ll tell you exactly how it is—because real trust doesn’t come from pretending, it comes from clarity. When there’s clarity, you know where you stand—and that’s your real power.

But trust doesn't mean agreeing on everything. In fact, the strongest teams I've been part of had one thing in common: they made space for pushback. Authentic dissent—someone who truly disagrees—forces deeper thinking and sharper solutions. A fake “devil's advocate” doesn’t do much. People can tell when it's just for show.

The best people I work with are the ones who challenge things. My daughter once walked in during a strategy session with colleagues I deeply respect and trust and asked, "Mom, why do you keep working with them if you disagree so much?" I had to laugh.

What sounded like arguing to her was actually our most productive mode—different perspectives pushing us toward better solutions. My rule is simple: if 51% agree, we go. What's the worst that can happen? If it fails, we pivot.

As Wayne Gretzky said, "You miss 100% of the shots you don't take." That's true in hockey, business, and life.

My son has played hockey since he was four. And like any young player, he’s had moments when he hesitated—skated past the shot, second-guessed himself, or waited just a little too long. The opportunity was right there… and then it wasn’t.

It’s the same for all of us. Waiting too long to act doesn’t keep us safe. It just makes sure someone else takes the shot we didn’t.

The reason I’ve been able to move things forward wasn’t because everyone agreed—it was because we had a shared goal, enough support, and just got it done. Boom. The quality of relationships improved dramatically when people knew they'd get the raw picture without sugarcoating. This trust was instrumental in the many wins we had around the world, developing ecosystems based on trust, collaboration, and different opinions.

Perfect consensus is a myth. If more people are in than out, that’s enough to move.

One study found that teams allowed to challenge ideas came up with 28% more real solutions than teams told to just stay positive.

I remember a brilliant Japanese student in my class at American University who, because of cultural norms, rarely challenged the professor. Participation made up 30% of the grade—and while others spoke just to be heard, his silence—despite being one of the smartest in the room—hurt his grade.

Why Feedback Moves Faster Than Consensus

When teams are allowed to challenge ideas, fresh perspectives emerge. A single dissenting voice can force the group to reexamine assumptions, leading to more innovative solutions.

As a result, blind spots shrink and teams that openly debate ideas are more confident in their decisions, which leads to stronger execution.

If we look at Pixar, one of the most successful creative companies in the world, it uses a process called “The Braintrust.” After every early cut of a film, the team gathers for a no-holds-barred feedback session. Nothing is off-limits. Every idea is questioned, no matter who it comes from. As a result some of the most beloved films of all time are created.

McKinsey research found that companies with diverse leadership teams that encouraged challenging discussions outperformed their peers by 36% in profitability.
